I was adjusting my reloader to be able to load some 9mm 100 gr loadssome thing wrong with. I finished setting up the dies and ran a case thru all stations (no powder or primer). I seated a bullet to the correct length and put it in my magazine and cycled it into the chamber. The bolt did not close completely with the barrel back about 1/2" of locking. I am not able to pull the slide back. Obviously, there is something wrong with the cartridge. It checked out ok in my gauge. Does anyone have an idea how to move the slide back?
